R. JAY GERKEN, CFA
Chairman, President and Chief Executive Officer


Dear Shareholder,
Stock returns were mixed during the period. The broader market, as measured by
the S&P 500 Index,/i/ posted modest gains due to strong corporate earnings,
positive economic news and continued low interest rates. However, sluggish job
growth, high-energy prices, and geopolitical concerns made many investors
cautious about some sectors of the market. These conditions benefited some of
the more defensive industries, such as consumer staples and utilities, and
hampered some of last year's better-performing sectors, such as technology and
materials. In general, value stocks outperformed growth stocks for the
six-month period, while large-cap stocks generally outperformed small- and
mid-cap stocks.

In recent months, the economy has shown clear signs of improvement. We've seen
employment statistics finally beginning to accelerate and consumer spending has
continued to be strong. The cyclical upswing seems to be gathering momentum and
interest rates have bounced off the very low levels that were engendered by an
accommodative Federal Reserve. The market has recently come under significant
pressure as the fears of higher interest rates and a slowing economy in China
have curbed investors enthusiasm for equities in spite of positive earnings
surprises for the majority of companies.

Within this environment, the funds performed as follows on the next page:/1/

/1/The fund is an underlying investment option of various variable annuity
   products. A variable annuity product is a contract issued by an insurance
   company where the annuity premium (a set amount of dollars) is immediately
   turned into units of a portfolio of securities. Upon retirement, the
   policyholder is paid according to accumulated units whose dollar value
   varies according to the performance of the securities within the sub
   accounts. Its objective is to preserve, through investment, the purchasing
   value of the annuity, which otherwise is subject to erosion through
   inflation. The fund's performance returns do not reflect the deduction of
   initial sales charges and expenses imposed in connection with investing in
   variable annuity contracts such as administrative fees, account charges and
   surrender charges, which if reflected, would reduce the performance of the
   fund. Past performance is no guarantee of future results.

                           PERFORMANCE OF THE FUNDS
                             AS OF APRIL 30, 2004

                                                        6 Months
Smith Barney Aggressive Growth Portfolio                  7.61%
Russell 3000 Growth Index                                 4.13%
Lipper Multi-Cap Growth Variable Funds Category Average   3.22%

Smith Barney Mid Cap Core Portfolio                       2.75%
S&P MidCap 400 Index                                      6.93%

   The performance shown represents past performance. Past performance is no
   guarantee of future results and current performance may be higher or lower
   than the performance shown above. Principal value and investment returns
   will fluctuate and investors' shares, when redeemed, may be worth more or
   less than their original cost.

   The performance returns set forth above do not reflect the reduction of
   initial charges and expenses imposed in connection with investing in
   variable annuity contracts such as administrative fees, account charges and
   surrender charges, which if reflected, would reduce the performance of the
   funds.

   All index performance reflects no deduction for fees, expenses or taxes. The
   Russell 3000 Growth Index measures the performance of those Russell 3000
   Index companies with higher price-to-book ratios and higher forecasted
   growth values. The S&P MidCap 400 Index is a market-value weighted index
   which consists of 400 domestic stocks chosen for market size, liquidity, and
   industry group representation. Please note that an investor cannot invest
   directly in an index.

   Lipper, Inc. is a major independent mutual-fund tracking organization.
   Returns are based on the six-month period ended April 30, 2004 and include
   the reinvestment of dividends and capital gains, if any. Returns were
   calculated among the 1,270 funds in the Lipper multi-cap growth variable
   funds category. Returns were calculated among the 1,000 funds in the Lipper
   mid-cap growth variable funds category.

Smith Barney Aggressive Growth Portfolio
For the six months ended April 30, 2004, the fund, returned 7.61%. The fund
performed better than the fund's unmanaged benchmark, the Russell 3000 Growth
Index,/ii/ which returned 4.13% for the same period. The fund also outperformed
the Lipper multi-cap growth variable funds category average, which returned
3.22%./2/

The portfolio outperformed its benchmark index due largely to sector
overweights and good stock selection in the healthcare and energy sectors, as
well as a significant underweight and good stock selection in the poorly
performing technology sector. In terms of individual holdings, the three
biggest positive contributors to portfolio performance were all in the
healthcare sector: biotechnology and biopharmaceutical firms Biogen Idec Inc.
and ImClone Systems Inc., and specialty pharmaceutical producer Forest
Laboratories,

   Returns are based on the six-month period ended April 30, 2004, calculated
   among the 1,270 funds in the fund's Lipper category including the
   reinvestment of dividends and capital gains, if any.

            2 Travelers Series Fund Inc. | 2004 Semi-Annual Report




Inc. While the portfolio's performance for the six-month period was quite
strong, some holdings detracted from performance. Two of the three biggest
detractors were holdings in the hard-hit technology sector -- memory chip
producer SanDisk Corp. and computer hard drive manufacturer Maxtor Corp. --
while another major detractor was biopharmaceutical company Chiron Corp./iii/

Smith Barney Mid Cap Core Portfolio
For the six months ended April 30, 2004, the fund returned 2.75%. The fund
underperformed the fund's unmanaged benchmark, the S&P MidCap 400 Index,/iv/
which returned 6.93% for the same period. The fund also lagged its Lipper
mid-cap growth variable funds category average, which returned 3.15%./3/

The main reason for the underperformance was the fund's reluctance to invest in
low-priced, high-volatility stocks. While these stocks appreciated strongly
over the last six months, the fund generally avoided investing in them due to
their high-risk nature. The fund focuses on stocks of higher-quality companies
with good fundamentals and favorable long-term outlooks, which we believe offer
better opportunities for long-term investors.

At the end of April, the sectors of the portfolio that were the most
overweighted versus the benchmark were industrials, technology and materials.
While we continue to emphasize these sectors, during the period we reduced the
portfolio's weighting in technology, specifically in the hardware area, in
favor of the industrial sector./v/

Our core philosophy continues to be based on investing in what we believe are
leading companies across a broad cross section of sectors and industries. Our
selection process focuses on companies that we perceive to have significant
advantages and excellent competitive positions in the marketplace.

Information About Your Fund
In recent months several issues in the mutual fund industry have come under the
scrutiny of federal and state regulators. The fund's Adviser and some of its
affiliates have received requests for information from various government
regulators regarding market timing, late trading, fees and other mutual fund
issues in connection with various investigations. The fund has been informed
that the Adviser and its affiliates are responding to those information
requests, but are not in a position to predict the outcome of these requests
and investigations.

   reinvestment of dividends and capital gains, if any.

RISKS:
Smith Barney Aggressive Growth Portfolio: Keep in mind, the fund may invest a
significant portion of its assets in small- and mid-cap companies which may be
more volatile than an investment that focuses only on large-cap companies.

large-cap stocks. Additionally, the fund's performance may be influenced by
political, social and economic factors affecting investments in companies in
foreign countries. The fund may use derivatives, such as options and futures,
which can be illiquid, may disproportionately increase losses, and have a
potentially large impact on fund performance.

 NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1. Significant Accounting Policies

The Smith Barney Aggressive Growth Portfolio and Smith Barney Mid Cap Core
Portfolio ("Fund(s)") are separate diversified investment funds of the
Travelers Series Fund Inc. ("Company"). The Company, a Maryland corporation, is
registered under the Investment Company Act of 1940, as amended, as an open-end
management investment company and consists of these Funds and thirteen other
separate investment funds: Smith Barney Large Cap Value Portfolio, Strategic
Equity Portfolio, Van Kampen Enterprise Portfolio, Smith Barney International
All Cap Growth Portfolio, Travelers Managed Income Portfolio, Pioneer Strategic
Income Portfolio, Salomon Brothers Strategic Total Return Bond Portfolio, Smith
Barney High Income Portfolio, MFS Total Return Portfolio, Smith Barney Money
Market Portfolio, AIM Capital Appreciation Portfolio, Smith Barney Large
Capitalization Growth Portfolio and SB Adjustable Rate Income Portfolio. Shares
of the Fund are offered only to insurance company separate accounts that fund
certain variable annuity and variable life insurance contracts. The financial
statements and financial highlights for the other funds are presented in
separate shareholder reports.

The following are significant accounting policies consistently followed by the
Funds and are in conformity with generally accepted accounting principle
("GAAP"): (a) security transactions are accounted for on trade date; (b)
securities traded on national securities markets are valued at the closing
prices in the primary exchange on which they are traded; securities traded in
the over-the-counter market and listed securities for which no sales prices
were reported and U.S. government agencies and obligations are valued at the
mean between the bid and asked prices; securities listed on the NASDAQ National
Market System for which market quotations are available are valued at the
official closing price or, if there is no official closing price on that day,
at the last sale price; (c) securities maturing within 60 days are valued at
cost plus accreted discount, or minus amortized premium, which approximates
value; (d) securities for which market quotations are not available will be
valued in good faith at fair value by or under the direction of the Board of
Directors; (e) interest income, adjusted for amortization of premium and
accretion of discount, is recorded on an accrual basis; (f) dividend income is
recorded on the ex-dividend date; foreign dividends are recorded on the
ex-dividend date or as soon as practical after the Funds determine the
existence of a dividend declaration after exercising reasonable due

            18 Travelers Series Fund Inc. | 2004 Semi-Annual Report




 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

diligence; (g) dividends and distributions to shareholders are recorded on the
ex-dividend date; the Funds distribute dividends and capital gains, if any, at
least annually; (h) gains or losses on the sale of securities are calculated by
using the specific identification method; (i) the accounting records of the
Funds are maintained in U.S. dollars. All assets and liabilities denominated in
foreign currencies are translated into U.S. dollars based on the rate of
exchange of such currencies against U.S. dollars on the date of valuation.
Purchases and sales of securities, and income and expenses are translated at
the rate of exchange quoted on the respective date that such transactions are
recorded. Differences between income or expense amounts recorded and collected
or paid are adjusted when reported by the custodian; (j) the character of
income and gains to be distributed is determined in accordance with income tax
regulations which may differ from U.S. generally accepted accounting
principles; (k) the Funds intend to comply with the applicable provisions of
the Internal Revenue Code of 1986, as amended, pertaining to regulated
investment companies and to make distributions of taxable income sufficient to
relieve it from substantially all Federal income and excise taxes; and (l)
estimates and assumptions are required to be made regarding assets, liabilities
and changes in net assets resulting from operations when financial statements
are prepared. Changes in the economic environment, financial markets and any
other parameters used in determining these estimates could cause actual results
to differ.

2. Management Agreement and Transactions with Affiliated Persons

Smith Barney Fund Management LLC ("SBFM"), an indirect wholly-owned subsidiary
of Citigroup Inc. ("Citigroup") acts as investment manager of the Smith Barney
Aggressive Growth Portfolio ("SBAG") and Smith Barney Mid Cap Core Portfolio
("SBMCC"). SBAG and SBMCC pay SBFM a management fee calculated at the annual
rates of 0.80% and 0.75%, respectively, of the average daily net assets of each
Fund. These fees are calculated daily and paid monthly.

Citicorp Trust Bank, fsb. ("CTB"), another subsidiary of Citigroup, acts as the
Funds' transfer agent and PFPC Inc. ("PFPC") acts as the Funds' sub-transfer
agent. CTB receives account fees and asset-based fees that vary according to
the size and type of account. PFPC is responsible for shareholder recordkeeping
and financial processing for all shareholder accounts and is paid by CTB. For
the six

            19 Travelers Series Fund Inc. | 2004 Semi-Annual Report




 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

months ended April 30, 2004, each Fund paid transfer agent fees of $2,500 to
CTB.

For the six months ended April 30, 2004, Citigroup Global Markets Inc. ("CGM"),
another indirect wholly-owned subsidiary of Citigroup, received brokerage
commissions totaling $5,383.

Most of the officers and one Director of the Company are employees of Citigroup
or its affiliates.

3. Investments

During the six months ended April 30, 2004, the aggregate cost of purchases and
proceeds from sales of investments (including maturities of long-term
investments, but excluding short-term investments) were as follows:

                                             SBAG        SBMCC
- -----------------------------------------------------------------
Purchases                                $115,791,535 $70,072,518

- ----------------------------------------------------------------

At April 30, 2004, the aggregate gross unrealized appreciation and depreciation
of investments for Federal income tax purposes were substantially as follows:

                                              SBAG         SBMCC
- --------------------------------------------------------------------
Gross unrealized appreciation            $ 106,288,449  $11,272,885
Gross unrealized depreciation             (128,558,547)  (3,459,147)
- -------------------------------------------------------------------
Net unrealized appreciation
 (depreciation)                          $ (22,270,098) $ 7,813,738
- -------------------------------------------------------------------

4. Repurchase Agreements

When entering into repurchase agreements, it is the Funds' policy that a
custodian takes possession of the underlying collateral securities, the value
of which at least equals the principal amount of the repurchase transaction,
including accrued interest. To the extent that any repurchase transaction
exceeds one business day, the value of the collateral is marked-to-market to
ensure the adequacy of the collateral. If the seller defaults and the value of
the collateral declines or if bankruptcy proceedings are commenced with respect
to the seller of the security, realization of the collateral by the Funds may
be delayed or limited.

            20 Travelers Series Fund Inc. | 2004 Semi-Annual Report




 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)


5. Futures Contracts

Securities or cash equal to the initial margin amount are either deposited with
the broker or segregated by the custodian upon entering into the futures
contract. Additional securities are also segregated up to the current market
value of the futures contract. During the period the futures contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking-to-market" on a daily basis to reflect the market value of
the contract at the end of each day's trading. Variation margin payments are
received or made and recognized as assets due from or liabilities due to
broker, depending upon whether unrealized gains or losses are incurred. When
the contract is closed, the Funds record a realized gain or loss equal to the
difference between the proceeds from (or cost of ) the closing transactions and
the Fund's basis in the contract. The Funds enter into such contracts typically
to hedge a portion of their portfolio. The Funds bear the market risk that
arise from changes in the value of the financial instruments and securities
indices.

At April 30, 2004, SBAG and SBMCC did not hold any futures contracts.

6. Capital Shares

At April 30, 2004, the Company had six billion shares of capital stock
authorized with a par value of $0.00001 per share. Each share of a Fund
represents an equal proportionate interest in that Fund with each other share
of the same Fund and has an equal entitlement to any dividends and
distributions made by the Fund.

Transactions in shares of each Fund were as follows:

7. Additional Information

The Funds have received the following information from Citigroup Asset
Management ("CAM"), the Citigroup business unit which includes the Funds'

            21 Travelers Series Fund Inc. | 2004 Semi-Annual Report




 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

Investment Manager and other investment advisory companies, all of which are
indirect, wholly-owned subsidiaries of Citigroup. CAM is reviewing its entry,
through an affiliate, into the transfer agent business in the period 1997-1999.
As CAM currently understands the facts, at the time CAM decided to enter the
transfer agent business, CAM sub-contracted for a period of five years certain
of the transfer agency services to a third party and also concluded a revenue
guarantee agreement with this sub-contractor providing that the sub-contractor
would guarantee certain benefits to CAM or its affiliates (the "Revenue
Guarantee Agreement"). In connection with the subsequent purchase of the
sub-contractor's business by an affiliate of the current sub-transfer agent
(PFPC Inc.) used by CAM on many of the funds it manages, this Revenue Guarantee
Agreement was amended eliminating those benefits in exchange for arrangements
that included a one-time payment from the sub-contractor.

The Boards of CAM-managed funds (the "Boards") were not informed of the Revenue
Guarantee Agreement with the sub-contractor at the time the Boards considered
and approved the transfer agent arrangements. Nor were the Boards informed of
the subsequent amendment to the Revenue Guarantee Agreement when that occurred.

CAM has begun to take corrective actions. CAM will pay to the applicable funds
approximately $17 million (plus interest) that CAM and its affiliates received
from the Revenue Guarantee Agreement and its amendment. CAM also plans an
independent review to verify that the transfer agency fees charged by CAM were
fairly priced as compared to competitive alternatives. CAM is instituting new
procedures and making changes designed to ensure no similar arrangements are
entered into in the future.

CAM has briefed the SEC, the New York State Attorney General and other
regulators with respect to this matter, as well as the U.S. Attorney who is
investigating the matter. CAM is cooperating with governmental authorities on
this matter, the ultimate outcome of which is not yet determinable.
